Mitigations are listed in the Workarounds section of this advisory. The attacker requires knowledge of the configured SNMP community string in SNMP version 1 and SNMP version 2c or a valid username and password for SNMP version 3.Ĭisco has released software updates that address this vulnerability. This vulnerability can be triggered by IPv4 traffic only. This vulnerability affects systems configured in routed and transparent firewall mode only and in single or multiple context mode. Note: Only traffic directed to the affected system can be used to exploit this vulnerability. The attacker must know the SNMP community string to exploit this vulnerability. An exploit could allow the attacker to execute arbitrary code and obtain full control of the system or to cause a reload of the affected system.
An attacker could exploit this vulnerability by sending crafted SNMP packets to an SNMP-enabled interface on the affected system. The vulnerability affects all versions of SNMP (versions 1, 2c, and 3) when enabled on a virtual or physical Cisco ASA device. The vulnerability is due to a buffer overflow in the affected code area. A vulnerability in the Simple Network Management Protocol (SNMP) code of Cisco Adaptive Security Appliance (ASA) Software could allow an authenticated, remote attacker to cause a reload of the affected system or to remotely execute code.
